Marcelo Tosatti 7819026eef KVM: MMU: Fix SMP shadow instantiation race ...

There is a race where VCPU0 is shadowing a pagetable entry while VCPU1
is updating it, which results in a stale shadow copy.

Fix that by comparing the contents of the cached guest pte with the
current guest pte after write-protecting the guest pagetable.
